Magnesium extraction of ferronickel slag processed by alkali fusion and hydrochloric acid leaching

Abstract: A research using ferronickel slag, the by-product of ferronickel production, as raw material for magnesium extraction has been carried out. It is essential to upgrade the value of ferronickel slag instead of used directly for reclamation materials. Moreover, accumulation due to increasing ferronickel demand as well as environmental contamination due to various potencially toxic elements contained in the ferronickel slag could be prevented. The general objective of this study is to utilize the… Show more

“…Furthermore, it has various opportunities to recycle [3]. Previous studies were conducted to utilize ferronickel slag as materials for cement [4] - [7], concrete [8]- [11], polymer [12], mortar [7], [8], magnesium [13] - [15], magnesium metal and ferro alloy [16] as well as for refractory [17]. The ferronickel slag contains SiO2 41 -46%, MgO 30 -41%, Fe2O3 10 -14%, Al2O3 2 -5%, Cr2O3 1,4 -1,9% and other compounds including rare earth elements (REE) in the amount of less than 1% [15], [18].…”

It allows ferronickel slag to be used as secondary raw materials for Si, Mg and REE as well through pyrometallurgy, hydrometallurgy, and combination of both processes.…”
